UNIX

 

 Unix  

“Write a shell script (to run on the Bourne shell) that takes a file name as argument and then compresses and decompresses the file with each of the following programs: bzip2 gzip zip For each of the compressing programs, the script notes the size of the file before and after compression. Then, the script displays a table showing the compression program, uncompressed size, and compressed size. Before using a compressing program to manipulate the file, your script must verify that the file actually exists under the current directory and is readable. You would probably need to research the UNIX command named set. Your script for this task must be named compr.sh. Make sure your script is user-friendly and follows common sense.”  

edit: an extra bit from the question i forgot to put in at the end “Your script for this task must be named compr.sh. Make sure your script is user-friendly and follows common sense. Here is a sample output (The $ is the shell prompt, and ff is the file name): $ compr.sh ff File: ff bzip2 174145 13976 gzip 174145 11746 zip 174145 11879 (Note: This output shows that, before compressing, the size of the file named ff is 174145 bytes. After compressing using bzip2, its size becomes 13976 bytes. After compressing using gzip, its size becomes 11746 bytes. After compressing using zip, its size becomes 11879 bytes. The table shows that, for file ff, the most efficient compressing program is gzip. Please note that the columns of the table must be left-aligned.)”   

Computer Science

A middle school has decided that it would like to make its students’ grades available to their parents via an online parent portal. In addition, this system will allow for important announcements to posted. The school has decided that a system will be developed inhouse to complete this project. in doing so, a number of processes need to be identified during the planning of the project.

Some of the processes for teachers can include:

Logging in to the system

Uploading grades

Posting announcements

Some of the processes for parents can include:

Log on to the system

Accessing and reading important announcements

Viewing student’s grades

Sending an e-mail to the student’s teacher via the system on questions regarding the student’s grades

Based on the scenario, choose any of the processes, for teachers or for parents, and complete the following tasks to create a report in a Microsoft Word document:

Define the problem and the current need in the given situation.

Create a hierarchy chart depicting the chosen situation.

Develop a flowchart and provide a brief explanation for it.

Develop an algorithm and provide a brief explanation for it.

Explain how arrays can be used within your choice.

Project1

 In this course you will prepare a project paper and summary presentation analyzing and evaluating the practical aspects of implementing information assurance change in an organization.  To begin your paper, review the systems security knowledge areas already selected for SyncSession Assignment1 (Security and Risk Management, Asset Security, Security Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, Software Development Security).   From the best practices area selected that is of interest of you as the basis of this Project (Change Management Program), 

 

  1. Domain where the need for change (your research problem) exists.
  2. Information Assurance best practice being evaluated or selected and the justification for the selection.  You can make a problem statement and justification.
  3. Summary paragraph of why you think it is important to study the change process as it relates to your selected Information Assurance best practice.  Be sure to address how the change process impacts your research problem.
  4. Annotated bibliographic references of three of the previous articles used in your analysis.  

Excel Chapter 6 Grader Project – Delta Paint | Exp19_Excel_Ch06_CapAssessment_Delta_Paint

 Exp19_Excel_Ch06_CapAssessment_Delta_Paint 

 

1

Download   and open the file named   Exp19_Excel_Ch06_Cap_DeltaPaint.xlsx. Grader has automatically added your   last name to the beginning of the filename.

2

Create   appropriate range names for Total Production Cost (cell B18) and Gross Profit   (cell B21) by selection, using the values in the left column.

3

Edit   the existing name range Employee_Hourly_Wage to Hourly_Wages2021.
  Note, Mac users, in the Define Name dialog box, add the new named range, and   delete the original one.

4

Use   the newly created range names to create a formula to calculate Net Profit (in   cell B22). Net Profit = Gross Profit – Total Production Cost.

5

Create   a new worksheet labeled Range Names, paste the newly created range   name information in cell A1, and resize the columns as needed for proper   display.

6

On   the Forecast sheet, start in cell E3. Complete the series of substitution   values ranging from 10 to 200 at increments of 10 gallons   vertically down column E.

7

Enter   references to the Total_Production_Cost, Gross_Profit, and Net Profit   cells in the correct locations (F2, G2, and H2 respectively) for a   one-variable data table. Use range names where indicated.

8

Complete   the one-variable data table in the range E2:H22 using cell B4 as the column   input cell, and then format the results with Accounting Number Format with   two decimal places.

9

Apply   custom number formats to make the formula references appear as descriptive   column headings. In F2, Total Costs; in G2, Gross Profit, in H2, Net Profit.   Bold and center the headings and substitution values.

10

Copy the number of gallons produced substitution values from the one-variable data   table, and then paste the values starting in cell E26.

11

Type   $15   in cell F25. Complete the series of substitution values from $15 to $40 at $5   increments.

12

Enter   the reference to the net profit formula in the correct location for a   two-variable data table.

13

Complete   the two-variable data table in the range E25:K45. Use cell B6 as the Row   input cell and B4 as the Column input cell. Format the results with Accounting   Number Format with two decimal places.

14

Apply   a custom number format to make the formula reference appear as a descriptive   column heading Wages. Bold and center the headings and substitution   values where necessary.

15

Create   a scenario named Best Case, using Units Sold, Unit Selling   Price, and Employee Hourly Wage (use cell references). Enter these values for   the scenario: 200,   30,   and 15.

16

Create   a second scenario named Worst Case, using the same changing cells.   Enter these values for the scenario: 100, 25, and 20.

17

Create   a third scenario named Most Likely, using the same changing cells.   Enter these values for the scenario: 150, 25, and 15.

18

Generate   a scenario summary report using the cell references for Total Production Cost   and Net Profit.

19

Load   the Solver add-in if it is not already loaded. Set the objective to calculate   the highest Net Profit possible.

20

Use   the units sold as changing variable cells.

21

Use   the Limitations section of the spreadsheet model to set a constraint for raw   materials (The raw materials consumed must be less than or equal to the raw   materials available). Use cell references to set constraints.

22

Set   a constraint for labor hours. Use cell references to set constraints.

23

Set   a constraint for maximum production capability. Units sold (B4) must be less   than or equal to maximum capability per week (B7). Use cell references to set   constraints.

24

Solve   the problem. Generate the Answer Report and Keep Solver Solution.

25

Create   a footer on all four worksheets with your name on the left side, the sheet   name code in the center, and the file name code on the right side.

26

Save   and close Exp19_Excel_Ch06_Cap_DeltaPaint.xlsx.   Exit Excel. Submit the file as directed.

Developing An Incident Communication Plan

                                                

Wk 11 Discussion -Developing an Incident Communications Plan

Developing an Incident Communications Plan*You are the CSIRT leader for a major ecommerce website, and you are currently responding to a security incident where you believe attackers used a SQL injection attack to steal transaction records from your backend database. Currently, only the core CSIRT members are responding. Develop a communication plan that describes the nature, timing, and audiences for communications to the internal and external stakeholders that you believe need to be notified.
